Resumen:
Neutrinos with energies above 1017 eV are detectable with the Surface DetectorArray of the Pierre Auger Observatory. The identication is eciently performed forneutrinos of all avors interacting in the atmosphere at large zenith angles, as well asfor Earth-skimming neutrinos with nearly tangential trajectories relative to the Earth.No neutrino candidates were found in 14:7 years of data taken up to 31 August 2018.This leads to restrictive upper bounds on their ux. The 90% C.L. single-avor limit tothe diuse ux of ultra-high-energy neutrinos with an E􀀀2 spectrum in the energy range1:01017 eV􀀀2:51019 eV is E2dN=dE < 4:410􀀀9 GeV cm􀀀2 s􀀀1 sr􀀀1, placing strongconstraints on several models of neutrino production at EeV energies and on the propertiesof the sources of ultra-high-energy cosmic rays.
